JOHN A. WALKER, OF MINNEAPOLIS, MINNESOTA.

SAD-IRON HEATER.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed y 17 1907. Serial No. 38 5258.

T 0 all whom it may concern:

Be it known that I, JOHN A. WALKER, a

citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Sad-Iron Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

' My invention has for its object to provide an improved sad ironheater especially adapted for use in connection with gas stoves, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in-the claim.

The invention is illustrated in the accompanying drawings, wherein. like characters indicate like parts throughout the several views.

Figure 1 is a plan view of the improved sad iron heater. Fig. 2 is a side elevation of he same, but with a portion thereof broken away. Fig] 3 is a detail view in horizontal section. taken on the line 91; at of Fig. 2 and Fig. 4 is a detail view in vertical section,

, taken on the line at .r of Fig. 2.

The numeral 1 indicates the body of the sad iron heater in the form of a hollow pyramidical shell and, as sh own in the drawings, l'iaving four flat sides. The base of the shell 1 is left open so as to permit the flame from the gas burner to enter the inside of the shell 1, thus heating it. This, in turn, heats the sad iron that may be placed upon it. Supporting flanges 2, are formed one on each flat side of the shell 1, and at the base thereof, for the purpose of supporting sad irons having but one pointed end, as indicated by dotted lines in Fig. 2. p 2 project approximately at right angles to the flat sides of'the shell 1, for the purpose of holding the bottom of the sad iron in contact with said sides. Stop lugs 3, formed one on each angle of the shell 1, connect the supporting flanges 2, one with the other, and project upward on said angles about onethird of the entire height of the shell 1.. Said lugs 3 limit the lateral movement of the sad As shown, the flanges iron, thereby assuring the proper position of said sad irons on the shell 1. Air passages 4 are formed near the vertex of the pyramid, as shown, one on each side of the shell 1, to

allow the escape of the products of combus tion, and to permit the hot flames to pass to the top of the shell. The vertex of the pyramid is formed with a hand-piece, shown in the form of a ring 5, for the purpose of lifting the heater on to or off from the stove.

Detachable crotch pieces 6 are provided for supporting double pointed said irons, as indicated. by dotted lines in Fig. 2. Said crotch pieces 6 are detachably supported on the sides of the heater, by interlocking engagement with the flanges 2 and lugs 3. The upwardly extended legs of the crotch pieces 6 are provided with bevel surfaces 7 for inter locking engagement with bevel surfaces 8 formed in the lugs 3, and the lower ends of the crotch pieces 6 are provided with bevel. surfaces J for interlockingengagement with the bevel surfaces 10 formed on the flanges 2. As is evident, by sliding the crotch pieces 6 upward on the sides of the shell 1, they may be disengaged. from. the flanges 2 and lugs 3. when it is desired to use the heater for heating sad irons h aving but a single point.

The device described is very simple and of very small cost; has in practice been found extremely e'lficient for the purposes had in view.

What I claim is:

The combination with a heater of the kind described having sloping sides forming a hollow pyramid, sup wrting flanges projecting from the base of said sides, stop lugs on said sides, said flanges and stop lugs having beveled surfaces, of crotch pieces having beveled surfaces for interlocking engagement with the beveled surfaces of said supporting flanges and stop lugs for detachably support ing said crotch pieces, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
